Why do Indonesian farmers build terraces to grow crops?

The terraces were built to make the most efficient use of shallow soil and to enable irrigation of crops by allowing runoff to occur through the outlet. The Inka people built on these, developing a system of canals, aqueducts, and puquios to direct water through dry land and increase fertility levels and growth.

Why do farmers do terrace farming?

Terraces reduce both the amount and velocity of water moving across the soil surface, which greatly reduces soil erosion. Terracing thus permits more intensive cropping than would otherwise be possible.

Why are the crops planted in a terrace?

terrace cultivation, method of growing crops on sides of hills or mountains by planting on graduated terraces built into the slope. Though labour-intensive, the method has been employed effectively to maximize arable land area in variable terrains and to reduce soil erosion and water loss.

Does Indonesia use terrace farming?

Terrace farming is commonly used in Asia by rice-growing countries such as Vietnam, Philippines, and Indonesia. Terrace farming prevents the washing away of soil nutrients by the rains. This leads to the growth of healthy crops. There are two types of terracing known as graded terracing and level terracing.

Why and how terraces are built?

Terraces are built on steep slopes to create flat surfaces on which crops are grown. They are built to prevent soil erosion.

Why is rice grown on terraces?

Graduated terrace steps are commonly used to farm on hilly or mountainous terrain. Terraced fields both decrease erosion andsurface runoff, and may be used to support growing crops that require irrigation, such as rice.

What is the purpose of rice terraces?

The structures’ original builders used stone and mud walls to carefully carve and construct terraces that could hold flooded pond fields for the cultivation of rice. They also established a system to water these plots by harvesting water from mountaintop forests.

What is terrace farming How does terrace farming help in conserving soil?

In terrace farming, a terrace is a piece of the sloped plane that is cut into a series of successively receding platforms, that resemble steps. This prevents rain from washing away soil, hence preventing soil erosion. Thus the correct answer is option C.

Is balcony and terrace the same?

Terrace: How to Tell the Difference. A terrace is an open space that can be attached or detached to a building. In contrast, balconies are small elevated platforms that are affixed to a given room in the house. Whereas a terrace can have multiple points of access, a balcony is typically only accessible through the room …

How does the terrace farming in slope areas help in land conservation?

Terracing technology reduces a field’s slope length and angle, so that soil erosion and soil fertility losses are minimal compared to a sloping land’s. The terrace’s flatness reduces runoff and enhances infiltration, which makes more moisture available to crops.

What crops are grown in terrace farming?

Some typical crops grown in terraces include barley, wheat, potatoes, corn, tea, olive, grape vines, coffee, and rice. A terrace is typically about 2-3 meters wide and 50-80 meters long. Some terraces flood with rain water, such as those used to farm rice.

What is terrace farming and where it is done?

Terrace farming is basically done in hilly or mountain areas because hilly areas are more liable to soil erosion and overflow of water. It has been made on steep slopes so that plane surfaces are used to grow crops.

What is terrace farming why it is popular in the mountains?

Terrace farming is carried out on the slopes of the mountains. Terraces are built on the slopes of the mountains to create flat lands to grow crops. Terrace farming is useful as it slows down the speed of water running down the mountains. This conserves fertile top soil.

What are terraces in geography?

In geology, a terrace is a step-like landform. A terrace consists of a flat or gently sloping geomorphic surface, called a tread, that is typically bounded on one side by a steeper ascending slope, which is called a “riser” or “scarp”.

Why are terraces built on steep slopes?

On steep land, terraces or broad channels are built perpendicular to the slope to reduce rill erosion by decreasing overland flow length. Sediment settles from overland flow as runoff travels at relatively low velocities along the gentle grades used in terraces.
